Subject: [FFmpeg-devel] [PATCH] libavcodec/qsvenc: Do not pass RGB solorspace to VPL/MSDK
Date: Mon, 13 Feb 2023 13:55:45 +0800
Message-ID: <20230213055545.535005-1-wenbin.chen@intel.com> (raw)
From: Wenbin Chen <wenbin.chen@intel.com>
When encode RGB frame, Intel driver convert RGB to YUV, so we cannot
set RGB colorspace to VPL/MSDK.
